RAPID MOISTURE TEST IN SAND TESTING

To determine the moisture content quickly in fresh sand and molding sand.

·       The instrument operation on the principle of the pressure generated between the moisture in the sample and the absorbent compound.

The instrument is light in weight and no need to any external supply.  The absorbent compound in the airtight bottle is provided in a box of rapid moisture tester.

· Proper way to hold the body and place the cap in the bottom of rapid moisture tester. Tight the U-clamp with the help of screw. Shack the instrument vigorously. This ensures immediate mixing of sand sample and the absorbent compound.

·Immediately the pointer of the gauge moves. Keep the instrument in a vertical position. Absorb the reading when the pointer stops further movements. The will give the % of moisture in the sample directly.

·Unscrew the handle and take out the cap. Throw away the used material. Clean the instrument for a subsequent test.

Precaution

·   Clean the instrument after use.

·   Do not expose sand sample.

·   Do not keep the absorbent compound exposed atmosphere.
